identifiers

[Ue-Li Pen]

If there is so much disagreement over how long the identifier is significant
to, why not say:

a) That the number of characters actually stored must be at least 7.
b) The length of the whole identifier is significant.

Eg:

foo_bar_three    on a machine which only stores 7 characters of the identifier,
                 would still be unique to: 
foo_bar_two      As although the first 7 characters are the same, the lengths
                  are different. 

This would at least ease the "identifier portability" problems somewhat.
And would certainly ease the port of OGRE to a machine which has only
7 characters significant in the identifier.. like CI-86..
